Ha, that's an interesting question. It would not greatly surprise me if I am the only one who has ever used this functionality, and it's been more than 20 years since I used it last :-)

I don't think there is any other example than those that are in the tests/ directory, none of which seem to go beyond calling DataOut::write_povray() instead of write_vtk() or whatever else the tutorial programs use. Just change the call in one of your favorite tutorial programs and see what you get and how that could be put through povray.

It would be interesting to get feedback -- maybe we could improve the documentation if you'd be interested in this!
